Perhaps mii-tool from the net-tools package might help you...
To set the speed automagically once the network starts up I personally
use this on my RTL-8139:
,----[ cat /etc/network/interfaces ]
| [...]
| auto eth0
| iface eth0 inet static
| address 192.168.0.1
| netmask 255.255.255.0
| up mii-tool -F 100baseTx-FD eth0
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
`----
Or, if you have a 2.4 kernel, you can use ethtool as Greg suggested.
HTH,
Flo
